Benefits
Address space randomization hinders some types of security attacks by making it more difficult for an attacker to predict target addresses. For example, attackers trying to execute return-to-libc attacks must locate the code to be executed, while other attackers trying to execute shellcode injected on the stack have to find the stack first. In both cases, the related memory addresses are obscured from the attackers. These values have to be guessed, and a mistaken guess is not usually recoverable due to the application crashing.

Famous quotes containing the word benefits:
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“While greedy good-doers, beneficent beasts of prey,
Swarm over their lives enforcing benefits ...”
—Robert Frost (1874–1963)
“When your parents are in political life, you aren’t normal. Everybody talks about the benefits, but I don’t know what the benefits are.... But I’d rather have that kind of mother than an overweight housewife.”
—Katherine Berman Mariano (b. 1957)
